Core Event: Citizen and Legislative Measures to Add ID Requirements for Mail-In Voting
Ballot measures slated for the November election in California, Arizona, Colorado, Nevada and other states would require a government-issued identification number—such as a driver’s license or the last four digits of a Social Security number—on mail-in ballots. In California, Proposition 39 proposes that voters provide either a photo ID in person or the last four digits of an ID number when voting by mail. Arizona’s Proposition 144 would amend the state constitution to mandate “valid government-issued proof of identity” for every ballot, regardless of voting method. Similar initiatives appear in Colorado and Nevada, while Republican-led legislatures have placed comparable voter-ID amendments on the November ballot in Arizona, North Carolina and Ohio.
Background & Context
The voter-ID proposals are part of roughly 30 voting-related questions on November ballots, about one-fifth of all state measures nationwide. Conservative activists have collected petition signatures to bypass Democratic-controlled legislatures in California, Colorado and Nevada, placing the issues directly before voters. The push echoes former President Donald Trump’s national voter-ID agenda, though he has not publicly endorsed the California measure. Parallel efforts include primary-structure amendments in Massachusetts and Alaska, and redistricting referendums in Missouri, Maryland, Colorado and other states.
Data & Statistics
- Voter-ID measures represent roughly 20 % of all state ballot initiatives this cycle.
- In the August primary, nearly 90 % of California ballots were cast by mail; fewer than 1 % (about 52,000 ballots) were rejected for signature mismatches.
- About 80 % of Arizona voters rely on mail-in voting, according to the Citizens Clean Elections Commission.
- An October AP-NORC poll found that 7 in 10 registered voters nationally favor requiring a valid photo ID at the polling place, with majorities among both Republicans and Democrats.
- Currently, only Georgia, Minnesota, New Mexico and Ohio require an identification number on mail-in ballots.
Official Statements & Responses
Republican Assembly member Carl DeMaio, whose Reform California group backs Proposition 39, argues that a citizen-driven win could pressure legislators to adopt “moderate and reasonable” ID rules nationwide. Arizona Representative Alex Kolodin, author of Proposition 144, frames the amendment as “common-sense” election security that enjoys bipartisan support.
Verbatim Quotes
- “Ballot measures have become a battle zone for the future of American democracy, including direct democracy itself,” — Chris Melody Fields Figueredo
- “Prop 39 is just another Trump power grab that is intended to make voting harder, less secure and more expensive for Californians,” — Brittany Stonesifer, voting-rights attorney, Common Cause California
Conflicting Reports & Gaps
Arizona’s Proposition 144 does not specify the mechanism for verifying IDs on mail-in ballots, leaving implementation details uncertain.
What’s Next
Voters in the six states will decide the fate of the voter-ID initiatives in November. If passed, the measures could reshape verification procedures for mail-in voting and set precedents for future ballot-driven election reforms.
